I'm literally about to pass out. I haven't slept yet because the seeing turned out to be good and the weatherman was totally wrong (forecasted clouds and chance of rain). It was clear all night. 

 

So, here are a few images of Jupiter with the Great Red Spot making it's trek across the face, as well as one of Saturn. The highest they climbed was 26 degrees, so I'm pretty happy that I was able to capture some detail. I used a ZWO 178MM camera with a  green CCD filter. Processing was quick and basic (Autostakkert, Registax, and a touch of Lightroom to lighten up a few of them). I'll probably give them more attention when I wake up later. There is such a glare on my laptop that I cannot tell how good or bad these really look. I should be able to tell later on this evening when there isn't so much light shining into this room.

 

It was nice to be out there for a change! The weather has been rough this year.

Lovely images Terry. Jupiter is so low in the sky here that I rarely dare to take a look at it wink.gif

Hey, thanks again everybody! Very much appreciated! I did a lot of captures, but the best were when the GRS was centered and Jupiter was at it's highest elevation of 26 degrees. It was hit and miss either side of that. The atmosphere was very steady at times, then start rippling randomly. Saturn came out a little better than I anticipated seeing as it was so low. It was really nice to have decent seeing for a change!

Did you use barlow lens?

Nicolas, no barlow was used for these. I plugged the camera into the axial port. The ZWO 178 pixel size is 2.4 microns which is a good match for the native f/15 Questar. I think the rule of thumb is the focal length for imaging should be anywhere from 3 to 7 times the camera's micron size. Anything beyond that is simply magnification of the image with no additional resolution added. Which is ok too if the seeing is good enough.

Beautiful images, Terry. You can see the GRS doing the “unraveling” that has recently been reported.

These Q scopes are just stunning in the right hands.

Wow, you had to have great seeing to get that detail out of a 3.5" Mak. Did it look close like that at the eyepiece?

The Saturn image is a close match to Saturn's visual appearance at 208x on May 26th.

Hey thanks again everybody! Been out of town so I'm late in my reply. Yes, it seemed like a good seeing night. I mainly set up for imaging and did not have an eyepiece with me for high power viewing. That being said, both Jupiter and Saturn looked very good visually on a small scale. I was surprised that I was able to capture several bands on Saturn as well as the dark area on top. The green ccd filter helped tremendousley. It really helps with contrast. I plan on buying a color camera with a large chip and small pixels. The large chip makes it so much easier to find the planet, then you can choose a moveable 640x480 region of interest and move it around as needed while imaging if your polar alignment is a little off. Thanks again for all of the compliments! V/R Terry

I have a QHY5-II mono guide camera that I'm using for my initial non-DSLR Lunar/planetary photography. I intend to get a color camera of that type later on. I've heard good things about the ASI-224, but I'll see what is available when I'm ready to buy.

But in the meantime using the QHY mono camera will let me get my field laptop, etc, set up and in use.

I have an ASI 224MC that I have used on only three or four occasions over the past four months. While the light gathering is impressive it is more than just a step up from using an iPhone coupled to the eyepiece, since now you’re dealing with software, laptops, and image stacking.

While I enjoy the idea of using it, frankly, it seems to be more frustrating to me than observing and “iPhone photography,” so after the weather clears up this summer I’ll know if it will have been worth the investment. They’re not expensive - I only paid about $220 for mine - but even after reviewing numerous videos and tutorials I’m still finding it frustrating, (which I’m sure is user error).

Observing has always been a joy and I wouldn’t let an attempt at more serious photography diminish that, so for me at least the jury is still out. (I’m sure this is inexperience speaking…).
